tional view taken from front to rear of the machine and illustrating the relative positions of the framework, traveling carriage, t 1 talizing mechanism and setting wheel. Figs. 3 and 4 are views chiefly in side eleva tion of the totalizing mechanism and adjacent parts. In Fig. 3 the controlling cam is shown in lowered position in which it shifts the setting wheel to active position. In Fig.

4 the cam is shown-in raised position in which it holds the cam in non. active osition. Fig. 5 is detail view illustrating the two possible positions of the controlling cam. Fig. 6 is an end view of the controlling cam. Fig. 7 is a plan View of the setting shaft with the setting wheels splined thereon. This figure illustrates the shifting action of the controlling canrand' controlling lever. Fig. 8 is a front elevation of the splined setting shaft, the controlling mechanism and two receiving or totalizing mechanisms. The controlling can]. isremoved in order to illustrate the operativc and non operative relationship between the setting wheels and the totalizing mechanisms. In the left side of Fig. 8 the setting wheel is shown to be out of line with the receiving wheels of the totalizer and. hence non operative thereon and in the right side is shown to be in line with a receiving wheel and hence. operative thereon. Fig. 9 is a side elevation of the machine partly in section illustrating among other things the escapemcnt of the carriage. Fig. 10 is a fragmentary sectional view taken on the line 10-10 Fig. 9.

Similar numerals refer to similar parts througl'iout the several views.

Referring to the drawings, 1 represents the framework of a typewriter having a laterally shiftable carriage 2 and vertically movable keys 3. Although various forms of escape ments may be employed, these IIICClHMIlSlllS being well known in the art, a suitable one is indicated more particularly in Figs. 9 and 10 of the drawings. In the design selected for illustration. the carriage is providedwith a To all whom ii ma y concern:

Be it known that I, HYMA 'ELI GOIDBEILG, a citizen of the United States, residing at Chicago, in the county of (look and State of Illinois, have invented a certain new and useful Improvement in Calculating-Machines, of which the following is a SPGClllGELtlUl].

My invention relates to calculating machines and to calculating attachments to typewriters, and is, in the main, a divisional fl-Pl')ll6ittl()l1 from the one filed by Inc May 28, 1904 Serial No. 210,158. In that application I have shown as a modified structure but have not-claimed in its specific form, a type of controlling mechanism in which the auxiliary setting wheels rotate whenever the valuating mechanism operates but are shiftable into two positions or stations in only one of which the auxiliary setting wheels are in line. with, and hence operative upon, the receiving wheels of the receiving or totalizing mechanism.

The object of the present invention is to provide a machine in which the auxiliary setting wheel or wheels always rotate but do not' always transmit the movement to the receiving wheels, such transmission depending u on. whether the auxiliary setting wh eel is shi ted laterally to a position in line with or to a position not in line with one of the sto ping points or stations of the receiving wheels.

Also in the former application I have shown a cam. which. cooperates with a spring to control the auxiliary setting wheel; the cam however is not ositive in. its action in the sense of being a le unassisted to positively determine whether there shall be connection or non connection between the setting wheel and the totalizing mechanism. In this present application I have provided a double cam. capable of occu ying two positions in one position positive y holding the setting means in connection with the tot-alizing mechanism and in the other position positively holding the setting means disconnected from the totalizing mechanisms, the

action of the cam thus being positive in e1ther circumstan ce.

I obtain my ob ects by the mechanism illustrated in the accompanying drawings in,

which:

Figure 1 is a general front view of my in vention in the form of an attachment. to a lvpewriter. Fig. 2 isfa fragmentary secrackAd) rigidly fastened thereto in a line parallel with the direction of travel. This rack is engaged by a. pinion 41 rigidly fastened to a shaft 42 pinioned in a bearing 43 u on the framework of thc machinc. idly attached to shaft 4'2 is an escupcment wheel 44 in position to vot'iperate wit h the two escapement do; :3 and 46 which are pivoted llig- .105

upon the stationary shaft or pin 47 These dogs are operated by a lever 48 connected to the universal bar 49 by means of the link 50. The universal bar is located in position to be operated by the different keys 3. The arrangement is such that when the keys are moved u and down the dogs 45 and 46 vibrate a out their pivot shaft 47 as a center and permit the intermittent rotation of wheel 44. A spring (not shown) is employed to move the carriage one ste each time it is released b the escapement ogs in the manner well nown in the art. The numeral keys are connected in an appropriate manner to the valuating mechanism 4. The precise construction of said valuating mechanism is immaterial, its function bein to drive shaft 5 and its attached pinion 6 di .erent amounts depending upon the value of the key temporarily in action. The valuating mechanism here indicated is fully described in the patent issued to me February 14, 1905, No. 782,554.

Wheel 6, which may be termed the valuating pinion, rotates always in the same direction and is mounted in the stationary bracket 7 secured to' bar 8 0n framework 1. Said pinion is beveled and adapted to rotate the gear wheels 9 and 10 which are alsd beveled and mounted upon a common shaft 11 journaled in the said stationar Wheel 9 in addition to its bevel portion has a spur gear portion which is adapted to operate upon the totalizing mechanism; and as said gears 9 and 10 are located on opposite sides "eno of said valuating pinion'the will berotated in opposite directions and w ll therefore have opposite effects upon the totalizing mechanism as will hereinafterappear.

Shaft 11 is free to rotate in bracket 7 and the main setting wheel 9 is loosely mounted on said shaft so as to rotate inde endently thereof. The bevel gear 10 is rigidfy fixed on shaft 11 for the purpose of rotating it whenever said gear is rotated by the valuating pinion 6 Said shaft is splined, and on itare mounted sleeves 12, which are free to shift thereon lengthwise thereof, but always rotate when shaft 11 rotates. Rigidly attached to, and

preferably integral with, the sleeves 12 are the auxiliary setting wheels 13, which are ada ted to mesh with the receiving wheels 14 of t e totalizing mechanisms, as the latter travel ast them. In this res ect, the action is simi ar to the action descril ied in my prior patents Number 741,961, dated October 20,

1903, and the above-mentioned Patent No.. 782,554dated February 14, 1905, and in the said com anion application Serial Number 210,158, ed May 28, 1904. In the present instance, however, both the auxiliary setting wheels and the. receiving wheels are thin 11' and the receiving wheels are s aced a suffielent distance apart to permit file set- I ting wheels to come between two adjacent receiving wheelslin theananner illustrated in bracket 7 w 'ch it is set by the operator.

ing Wheels and the rotation of the setting wheels will not be imparted to them. Thus for a given position or station of the totalizing mechanism, an auxiliary setting wheel is capable of occupying two positions, in one of which it IS in line with, and meshes with, a given receiving wheel, and in theother osition is out of line with such receiving w eels and isv therefore out of engagement therewith. i

The shifting of the setting wheels on their splined shaft is effected by means of shifting levers 15, which, in'the present instance, are pivoted on the upright posts 16 on the brackets 7. Said levers are provided'With ins 17 which are adapted to be received wit in the annular grooves 18 of sleeves 12 in such manner that when said levers are rotated about their pivots, said sleeves and the setting wheels 13 thereon will be shifted lengthwise of shaft 11 without interfering with the rotation of said sleeves and setting wheels. Said levers also have rigidly secured thereto pins 19 by which said levers are operated. In the present construction said pins 19 have heads 20 formed thereon, adapted to be engaged by above mentioned is double; and in order togive the operatorhis choice as to whether an auxiliary setting Wheel shall or shall not operate the receiving wheels as they pass by, said cam is so constructed as to be capable of occupying two positions in one of- WlllCll it will cause the auxiliary setting wheels to assume an operative position and in the other of which it will cause said setting wheels to assume a non operative position relatively to the definite stations or rest points or stopping points of the receiving wheels of the totalizing mechanism. A suitable construction for a cam capable of obtaining my purpose is here shown, especially in Figs. 3, 4, 5 and 6, In the resent design Ihave made it possible for saicl cam to assume two positions by pivoting the same upon the pins or trunnions 22 jonrnaled in the side walls 23,23, of the total izing mechanism. A pin 24 is secured to one of said side walls 23 in such manner and in such position as to act upon the spring 24" u on cam 21 and retain it in the osition in T e arrange ment is such that when the cam is rotated to one or the other position by the operator, it will there remain until the position is altered by the operator. Said cam is so con structed with reference to pin 19 and head 20 that when said cam is in lowered position as illustrated in Fi 3 and in full lines, Fig. 5, the head 20 will %e retained between the cam surfaces and 26, while if the cam is rotated to raised osition as illustrated in Fi 4 and in dotted ines Fig. -5, said head 20 W1 1 be retained between the surfaces 27 and 26. When within one of these pairs of surfaces the controllin lever 15. which carries the pin head 20 will be rmly and positively held in such 0- sition as to hold its setting wheel 13 in me with the stopping points of the receiving wheels 14, and when said in head is within the other of these pairs 0 cam surfaces on cam21 lever 15 will be ositively held in such position as to hold sai setting wheel out of line with the stopping points of said receiving wheels. It is thus evident that the action of the cam on the pin is positive in both positions of said cam. The ends of the cam are of course slightly byeled so that the cam surfaces will find the pin'head upon coming up to it in the course of their travel.

For convenience,-the form of totalizing mechanism here indicated is the one which is deseribedin detail in my aforesaid atent No. 7 41,961, and also in the aforesai companion application. The s irit of this in vention, however, is not con ned to this form of totalizing or receiving mechanism, for a totalizing mechanism equally suitable for use in the; resent machine is shown and de-- scribed in, atent Number 782,605 issued to me February 14, 1905. Both of these totalizing mechanisms are reversible, that is, are adapted to add when the receiving wheels are rotated in one direction and to subtract when they are rotated in the opposite direction; .but a non reversible receiving mechanism might be employed and yet permit the mechanism'to accomplish some'of the advanta geous results of this invention; for example," if the setting wheel 9 were entirely omitted 'and only a single wheel 13 were employed, the cam device would still be operative to control such remaining wheel 13 to determine whether or not connection should be established between it and the totalizing mechanism and if two setting wheels 13 were employed, addition could be performed in the same horizontal line of typewriting, because said wheels 13, both rotate in the same direction.

In the present design, the manner of mounting the totalizing mechanisms and causing them to travel across the setting wheels is the same as that shown in .my companion application and the aforesaid patents No. 741,961, and. 782,554. Said totalizing mechanisn'ls are mounted upon the slide 29 which is sliiftable upon the guide-bar 8 hereinabove mentioned, said guide-bar running parallel to the direction of travel of the typewriter carriage 2. The step by step movement of the carriage is imparted to said slide by means of the depending arm 30 extending from the carriage into the socket or keeper 31 on said slide 29.

The operation of the presentmachine is closely analogous to the operation of the one described in my aforesaid companion application, except that with the present device the auxiliary wheels 13 rotate every time the valuating inion 6 rotates. The carriage, of course, an hencethe totalizing mechanisms, travel from right to left with a step by step movement, the stopping points or station being definite and being the same each time the carriage repeats itsjourney. As the totalizing mechanism ap roaches in its usual direction of travel, it rst reaches the main setting wheel 9, which rotates in, say, a positive direction to cause addition. If, now, the operator desires the auxiliary setting wheel to subtract out the same or a different num ber from the one set up by the main setting wheel, he throws cam 21 to such position that when it engages head 20, of in 19, it throws lever 15' to such position tiiat its auxiliary setting wheel 13 will be shifted to a point in line with one of the stopping points or stations of the receiving wheels of the totalizing I a difference will be shown onthe totalizing mechanism. If the difference represents a positive number, the totalizing mechanism may then be clearedthat is to say, the

wheels thereof may be returned to zero by printin that number at the side in such po-' sition that the receiving wheels will be in en gagement with the second auxiliary setting wheel at the time of printing the number.

It will be evident thatone, or more than one, auxiliary setting wheel may be employed in the machine, and that one or more than one totalizing mechanisms may be employed. It is also evident that one auxiliary setting wheel may be employed with one or more than one totalizing mechanism, and also that a plurality of auxiliary setting wheels may be employed with one or more than one totalizing mechanism.

What I claim as new and desire to secure by Letters Patent, is; 1. In a calculating machine .the combina tion of a rotatable and shiftable setting wheel; a totalizing mechanism adapted to travel step by step across said setting wheel for coming into connection therewith, said totalizing 1110s vhanism stopping at definite stations in its :step by step movement, and said shifting said setting wheel into a setting wheel being shiftable to a point where of and to a point where its rotation will be non transmissible to the totalizing mechanism at the same station thereof; and means traveling inunison with the totalizing mechanism for shifting said setting wheel to a predetermined one of its two described positions.
